Compression-Actuated Multi-Cycle Circulation Valve |
| 摘要 |
A downhole tool conveyed via tubing within a wellbore at a wellsite comprises a hydraulic tool driven by fluid pumped to the hydraulic tool via the tubing. The downhole tool further comprises a valve in fluid communication between the tubing and the hydraulic tool. The valve is configurable in the wellbore between an expanded position, establishing a bypass diverting at least a portion of the pumped fluid away from the hydraulic tool, and a compressed position, closing the bypass. |
